Cylinder Hydrostatic Testing
Cylinder Hydrostatic Testing
Sovereign Extinguishing offer 10-year Cylinder Hydrostatic Testing with a time saving service exchange programme.
Cylinder hydrostatic testing is a mandatory process for maintaining the safety and compliance of compressed gas cylinders used in fire suppression systems. Sovereign Extinguishing provides professional cylinder hydrostatic testing to ensure the safety and compliance of fire suppression cylinders. Compressed gas cylinders require testing every 10 years to confirm they remain safe and fit for purpose.
After a decade of use, all fire suppression cylinders, including FM-200, 3M™ Novec1230 TM Fire Protection Fluid, Inert Gas and CO₂, must undergo hydrostatic testing. Our 10-year testing service verifies that cylinders meet safety standards, preventing potential failures and ensuring continued system reliability.
Regular hydrostatic testing is essential for maintaining compliance and extending the lifespan of your systems . Our service exchange programme minimises disruption by replacing tested cylinders with refurbished equivalents, keeping your system operational at all times.
At Sovereign Extinguishing, we provide service and maintenance for fire suppression systems across the UK, regardless of the original installer or service provider. All testing is carried out in line with British Standards and industry regulations. With accreditations from BAFE, FIA, and Cyber Essentials, you can trust us to maintain the integrity of your fire suppression system.

10-Year Cylinder Hydrostatic Testing
Compressed gas cylinders must undergo testing every 10 years to confirm they are safe and meet regulation limits. Hydrostatic testing works by checking the structural integrity of high-pressure cylinders, ensuring they can withstand their maximum working pressure without failure.
Hydrostatically tested cylinders receive a current test stamp and are reconditioned before being returned for use. If a cylinder has passed the pressure test, it is recertified and compliant. Failed cylinders must be removed from service.
Sovereign Extinguishing offers testing for fire suppression cylinders.. Our facilities allow us to handle the whole process efficiently.
What is Hydrostatic Testing?
Hydrostatic testing involves filling a cylinder with water and placing it in a pressurised chamber. The water pressure inside the cylinder increases, causing it to expand slightly. This process assesses whether the cylinder’s design pressure limit has been exceeded.
Cylinder expansion beyond regulation limits indicates failure. Compliant cylinders are dried, fitted with a new or refurbished valve, and returned to service. This periodic inspection ensures the continued safety and functionality of pressure vessels.
What are the Standards for Cylinder Hydrostatic Testing?
Cylinder Hydrostatic Testing is mandatory and must be performed every 10 years according to Pressure Equipment Regulations 1999. Associated standards also include BS EN 1968:2002 and the current FIA guidelines.
Hydrostatic Testing must be undertaken by individuals or companies accredited to EN ISO 17020.
How Does Cylinder Hydrostatic Testing Work?
Hydrostatic testing involves the filling of cylinders with water and placing the filled cylinders into a water filled pressure chamber. This causes the water pressure inside the cylinder to increase and the cylinder to subsequently expand. This is called Hydrostatic Testing.
Cylinder expansion of less than 5% is within regulation limit and allows for recertification. Compliant cylinders are dried out, stamped with certification and dated with test details. The cylinder is then reconditioned and either a refurbished or new valve is fitted.
Sovereign Extinguishing Cylinder Exchange
The testing of cylinders can be a disruptive process, as the cylinders must be taken away, discharged, tested, recharged and redelivered onsite. This process is not only costly in money, but time, possibly leaving a Fire Suppression System out of action for two weeks or more.
Therefore, Sovereign Extinguishing offer a service exchange programme. Our customers ‘exchange’ their cylinders for an equivalent refurbished one to save time and money. We can complete the process with minimum inconvenience, with downtime reduced from weeks to just a few hours.
All we require is a photograph of the cylinder valve, the label, and the height of the cylinder outlet from the floor. From there, our team handle the whole process and ensure that your Fire Suppression System maintains compliance for your safety.
The Advantages of Hydrostatic Testing
Hydrostatic cylinder testing ensures safety and compliance for fire suppression cylinders.. Regular testing prevents the risks associated with failed cylinders, which will compromise fire suppression systems.
The Sovereign Extinguishing service exchange programme allows you to replace cylinders quickly, preventing extended downtime. Testing involves thorough inspection, ensuring high-pressure cylinders meet safety requirements.
Certified fit for use, tested cylinders maintain the reliability of your fire suppression system. The whole process is efficient, ensuring regulation limits are met while minimising disruption.
